RAD MAG Complete Install Guide - Prep, Mount & Wire

Best bond, first time

A rock-solid hold starts with clean glass

Every RAD MAG receiver mount now ships with a professional isopropyl alcohol prep wipe - so the adhesive grips bare glass instead of dust and film. One quick wipe means the strongest, longest-lasting bond.

Stronger bond

Easier install

Right first time

Your 30-second windscreen prep

1

Warm the glass

Glass should feel warm - ideally 20°C-38°C. If it's cold, run the defroster or a hairdryer over the spot for 1-2 minutes.

2

Wipe & buff dry

Clean with the included isopropyl wipe, then buff the wet area dry straight away with a clean microfibre cloth.

3

Press & mount

Onto buffed-dry glass, press the 3M VHB firmly from the centre for the strongest bond.

Complete install guide

Step 01 - Prep

Warm the glass, wipe & buff dry

Glass must feel warm - ideally 20°C-38°C. VHB will not bond to cold glass, so warm the spot with your defroster or a hairdryer for 1-2 minutes first. Clean it with the included isopropyl wipe, then buff the wet area dry straight away with a clean microfibre cloth. Don't let it air dry - wiping while wet lifts the oils off the glass.

Step 02 - Mount

Press firmly, wait 36-72 hrs

Press the receiver from the centre outward for 30 seconds minimum. Leave it undisturbed for 36-72 hours (72 hours for Redline 360C detectors) - the adhesive needs that time to cure before it takes the weight and leverage of the detector arm.

Step 03 - Wire & drive

Connect power, snap in

Powered mounts: connect switched 12V via mirror tap or fuse tap (see below). Snap the detector arm into the mount and start driving.

Step 03 - wiring detail

Two ways to power your mount

Mirror tap (easiest)

Plug spade connectors into the power loom behind your rear-view mirror - no fuse box trip, no wire cutting. Drop the mirror cover, identify switched 12V + ground, slip the spades on, tuck the tail along the headliner and refit. Fully reversible.

Fuse tap (bare wire)

Run a switched 12V feed from a fuse slot in your fuse box and bolt the black ring terminal to a bare-metal chassis bolt for ground. Insert a 2A fuse in the slot farthest from the blade. Route wires along the headliner and down the A-pillar for a permanent, tidy result.

Before you connect

Always confirm switched (not constant) 12V with a multimeter before wiring - constant power drains your battery overnight. Mirror tap ends in two flat spade plugs; fuse tap ends in a red wire + black ring terminal.

Pro tip

Not sure? Get it installed.

Any local car audio shop can install the powered mount in under 15 minutes. If you'd rather have it done right the first time, that's the move - and it keeps the 30-day guarantee fully intact.
